Mangroves also provide ideal locations for aquaculture, which is currently “the fastest growing food-producing sector in the world”, though often mangrove forests are destroyed for this purpose. When we looked at example mangrove forests in different locations around the world, we found that the density and extent of the mangroves varied dramatically. These unique forest ecosystems provide a number of additional environmental benefits, as well. The world has lost around 3.6 million hectares (ha) of mangroves since 1980, equivalent to an alarming 20 percent loss of total mangrove area according to FAO’s recent mangrove assessment study, entitled The world’s mangroves 1980-2005. Twenty percent of the world’s mangroves lost over the last 25 years: Rate of deforestation slowing, but still a cause for alarm What definition has FAO used for this study? The world has lost around 3.6 million hectares (ha) of mangroves since 1980, equivalent to an alarming 20 percent loss of total mangrove area according to FAO’s recent mangrove assessment study, entitled The world’s mangroves 1980-2005. Because they are located in coastal zones, where population densities are typically high, mangrove areas are frequently converted to other uses, including fish and shrimp-farming, agriculture, salt production and urban development. Mangroves grow on both the western and eastern coasts of Africa. Aim Our scientific understanding of the extent and distribution of mangrove forests of the world is inadequate. Around 20 percent of the world’s mangrove forests have disappeared during the past 25 years as a result of over-exploitation and conversion to other uses, according to a new FAO study. About 90 percent of the mangrove forest cover is found in developing countries, but is nearing extinction in 26 countries. “Other studies suggest that the number of Sundarbans mangroves has remained stable or decreased very slightly over the last few decades, and this is also what we found,” said Awty-Carroll. Mangroves are evergreen trees and shrubs that are well adapted to their salty and swampy habitat by having breathing roots (pneumatophores) that emerge from the oxygen-deficient mud to absorb oxygen. Kenya’s closed canopy forest cover currently stands at about 2 percent of the total land area, compared to the African average of 9.3 percent and a world average of 21.4 percent. They stretch into India, Burma, and south-east Asia. 275,000. The total area is nearly 10,000 km2. There are 15.9 million hectares (over 60,000 square miles) of mangrove forests in the warm waters of tropical oceans all over the world. One of the largest mangrove forests in the world is the Sundarbans, which straddles the border of India and Bangladesh. That's the good news. Still, during the same time frame the annual rate of mangrove deforestation dropped from around 185 000 ha per year in the 1980s to 105 000 ha/yr during the 2000-2005 period, it added. In some places, such as Senegal, virtually … Mangroves constitute only 0.5 percent of forest area worldwide, but millions of people depend on them for food, income and protection of coastlines against erosion. The report, to be published next January, will provide an overview on mangrove vegetation and species, uses and threats in addition to information on mangrove areas and area changes over time. Since 1980, about one-fifth of the world’s mangroves have disappeared. Introduction. The available global mangrove databases, compiled using disparate geospatial data sources and national statistics, need to be improved. Mangrove forests grow where saltwater meets the shore in tropical and subtropical regions, thus serving as an interface between terrestrial, fresh-water and marine ecosystems. 7. However, over the past half-century, more than 70 percent of mangrove forests in China have vanished because of human activity. Our EIN or tax ID is 45-3714703. Despite these clear benefits, since 1980 the world has lost approximately 20 percent of its mangrove forests. This is a modified press release from FAO. In addition, it is at the… And every year we lose roughly another 1 percent. The bad news: Mangroves face numerous threats — 35% were lost between 1980 and 2000, and since the turn of the 21st century almost 1 in 50 of the remaining mangrove forests has been cut down. There are movements in place to encourage more sustainable forms of aquaculture that complement the local environment instead of destroying it, but this is still not the norm. Mangroves are salt-tolerant forest ecosystems commonly found along sheltered coastlines, in deltas and along river banks in the tropics and sub-tropics. Mangroves in India are 3 percent of its total geographical area. Our study confirms earlier findings that the biogeographic distribution of mangroves is generally confined to the tropical and subtropical regions and the largest percentage of mangroves is found between 5° N and 5° S latitude. Mangroves help prevent and reduce coastal erosion, providing nearby communities with protection against the effects of wind, waves and water currents. That’s the good news. Fifty percent of the world’s mangroves have disappeared in the past half-century, victims of rising sea levels; oil spills and other pollution; demand for timber; and clearing to make way for shrimp and crab fishing, coastal infrastructure, and urban expansion. Although human pressures are a major threat, little is known about the governance conditions that facilitate long-term conservation and restoration […] The key findings of the report were presented today at the Conference of the Parties to the Ramsar Convention on Wetlands, which began yesterday in Kampala, Uganda (8-15 November 2005). Mangrove habitat loss has put 16 percent of mangrove plant species and 40 percent of mangrove-associated animal species at an elevated risk of extinction in the world (Polidoro et al., 2010). 20% of the world’s mangrove forests have disappeared since 1980 according to a new study by the Food and Agriculture Organization of the United Nations (FAO). Apple commits to be 100 percent carbon neutral for its supply chain and products by 2030 Already carbon neutral today for corporate emissions worldwide, the company plans to bring its entire carbon footprint to net zero 20 years sooner than IPCC targets The Montague wind farm in Oregon is one of Apple’s largest projects at 200 megawatts and powers Apple’s Prineville data center. Mangrove swamps also provide habitat for fish, crabs, mudskippers and egrets. Home to many species. Only 6.9 percent of mangrove forests are protected by law. The bad news: Mangroves face numerous threats — 35% were lost between 1980 and 2000, and since the turn of the 21st century almost 1 in 50 of the remaining mangrove forests has been cut down. D. 35%. These areas usually get rain year-round, typically more than 70 inches (1,800 millimeters) a year, according to the Encyclopedia Britannica. It is characterized by low tree diversity, almost exclusively mangroves, with a low broken canopy. The term \"rainforest\" has a wide classification.
